Yeah. sadly it won't because Igor is a generous and humble man. He would give her to be your sex toy like a gift and he would be very happily actually if you took her virginity. He is a one of a kind amazing friend/acquaintance. Definitely worth sharing a little bit of the girls at home to treat him well. Hospitality matters.
I think you can fun with Omar though, You will definitely get to do an anal scene with both his wife and daughter in the future and in right front of him. Damn, I keep remembering his stupid face and pussy behavior in the bedroom and kitchen when I'm writing this. There are people like him in the real world. This game relates so much to life. Sharing with him is also possible in the future, although I won't be giving anything to this loser. He probably can't even get it up.
As for the NTR idiot in the thread. You can block sharing as soon as you start a new game, so don't even get any option from the very beginning. Unlike other devs, this dev let people choose what they want to do, and this also helps in experimentation.
